No. If they replaced the whole motor, nothing to worry about. Ride it and enjoy... though you do have the 600 mile service/head re-torque to not ignore. Do I have your VIN in the Registry thread(?); https://www.guzzitech.com/forums/threads/v7-registry-picture-thread-add-your-bike.9108/So, do I need to get another 300 miles on it in the next two to three weeks to verify that the new engine is good?
